THOMAS J. MULVAI-IILL, OF WATERTQWN, MASSACHUSETTS, ASSIGNOB. TO BOSTON WOVEN HOSE & RUBBER COMPANY, OF CAMBRIDGE, MASSACHUSETTS, A CORPORA- TION OF MASSACHUSETTS.

FOUNTAIN BRUSH.

Application filed January 26, 1923. Serial No. 615,001.

This invention relates to a fountain brush comprising a hose nozzle of improved construction and a brush for engaging the water stream issuing from the nozzle and converting it into a fine spray with which polished surfaces, such as the varnished sur faces of automobiles may be washed without injury to the polish or varnish.

In the drawing illustrating the preferred form of the invention:

Fig. 1 is an elevation of a hose nozzle embodying this invention;

Fig. 2, a similar view partly in sect-ion, and

Fig. 3, a plan of the nozzle shown in Fig. 1.

Referring to the drawing, the hose nozzle illustrated therein comprises a body portion 10 having the union 12 for coupling the nozzle to the end of a hose. The flow of water through the nozzle is controlled in the present instance by a needle valve 14.

In order to cause the water stream to emerge from the nozzle in sheet form, the latter is provided with a threaded mouth 16 and a cap member 18 screwed therein. The cap member 18 is provided with an elongated slot or orifice 20 for causing the water stream to emerge in a sheet, preferably of fan shape.

The force of the water stream emerging in sheet form is materially diminished, and for some purposes, it, may, with advantage, be played directly against the object to be washed.

For washing highly polished surfaces, it is desirable that the water stream be con verted into the form of a fine spray, and for this purpose the nozzle has mounted thereon a brush 22 having a large number of bristles 23. The brush 22 is arranged to extend across the nozzle in the plane of the water outlet slot 20, in position to be en gaged bv the sheet-like water stream, and in the illustrated construction is secured to lugs 24, 25 arranged to project laterally from the body 10 of the nozzle, being preferably cast integrally therewith. The lugs 24, 25, are provided with holes through which the opposite ends 26, 27 of the brush 22 are extended and fastened by screws 28, 29.

The arrangement of the lugs 24, 25, and of the elongated slot or orifice 20, when the cap member 18 is screwed tightly into the threaded mouth 16 of the nozzle, is such as to cause the sheet of water to impinge upon the brush, and to be converted thereby into the form of a fine spray. In this form the water stream may be directed against highly polished or varnished surfaces without liability of injuring them. The hose nozzle constructed as herein shown is very useful in washing automobile bodies.

lVhile the preferred form of the invention has been illustrated and described, it will be observed that the same may be embodied in other forms within the scope of the following claim.

Having thus described the invention, what is claimed is:

In a device of the character described, in combination, a hose nozzle having a threaded mouth at the discharge end thereof,- a cap member in threaded engagement with said mouth and havingan elongated slot, lugs projecting from opposed sides of the nozzle, and a brush secured to the lugs and extending across said slot in position to engage the stream emerging therefrom.

In testimony whereof, I have signed my name to this specification.

THOMAS J. MULVAHILL.
